An electroscope can be used to determine the polarity of an electrostatic charge?
Yes, an electroscope is a device that detects the presence of an electrostatic charge and can indicate the polarity of the charge through the direction of deflection of its metal leaves. If the leaves separate, it indicates a charge is present.
Why is it not possible to charge a metal rod held in hand by rubbing with cloth?
When a metal rod is held in hand, it gets grounded, which means the excess charge created on it during rubbing gets neutralized by the body's conducting properties. This prevents the accumulation of charge on the rod, making it unable to hold a charge.
Why can you produce a static discharge if you touch a metal doorknob after walking on a wool carpet?
Walking on a wool carpet can cause the buildup of electrostatic charge on your body. When you touch a metal doorknob, the excess electrons from your body discharge to the knob, creating a static shock.
Why does a metallic comb does not get charge when you rub it with your hair?
Metal is a good conductor of electricity, so any charge generated from rubbing the comb with hair will quickly dissipate through the metal. The electrons are free to move within the metal, equalizing any charge imbalance.
How does an electrostatic precipitator work and what does it remove?
An electrostatic precipitator works by using an electric charge to remove particles like dust and smoke from the air. The device attracts the particles to metal plates, where they collect and can be removed.

Can electricity moves?
Yes. Electromagnets move solid metal objects. Electrostatic charge moves solid objects in electrostatic scrubbers.etc. F= ma = eE where E is the electric field and e the charge. acceleration a = eE/m.

Why is it difficult to put a charge on a metal rob by rubbing it with wool?
Since metal is a conductor the electrons easily transfer throughout the entire object therefore the temporary charge put on one part by the wool will discharge by traveling through the rod to your hand, thus grounding it.

What are ionic compound and what charge do they carry?
Ionic compounds are compounds composed of ions held together by electrostatic forces. These compounds typically consist of a positively charged metal ion and a negatively charged nonmetal ion. The metal ion carries a positive charge, while the nonmetal ion carries a negative charge.
What kind of charge is rubbing your feet on the carpet?
Rubbing your feet on the carpet generates static electricity, which can result in a buildup of negative charge on your body. When you touch a metal object or another person, the excess electrons can transfer, causing a mild electric shock.
Can you electrify a metal rod by rubbing it while holding in your hand?
Yes, you can electrify a metal rod by rubbing it while holding it in your hand, but the effectiveness depends on the materials involved. Rubbing the rod with an insulating material can transfer electrons, causing the rod to become charged through the process of triboelectric charging. However, since metal is conductive, any charge that accumulates may quickly dissipate into your body or the surrounding environment, limiting the overall charge you can achieve.
What are main functions of electroscope?
An electroscope is used to detect the presence of electric charge on an object by showing the divergence of its metal foil leaves due to electrostatic repulsion. It can also be used to determine the type of charge (positive or negative). Additionally, an electroscope can be used to demonstrate the principles of electrostatic induction.
